My city is called Logana, it is floating above the blue and deep sea. Where the floor is actually transparent for you to be able to see what’s underneath. All of the inhabitants are very friendly and charismatic. They all have about the same age. Cars and public transport are prohibited because they contaminate the environment, so people have bikes.
Animals and humans have a really strong bond of co-existence, so violence doesn’t exist. But once you are a member of Logana, you have to respect all of its rules: using violence can’t be permitted and you have to be friendly and gentle. The buildings are waterproof because it is in the sea, if a tsunami comes its residents will be able to survive.
And sometimes when citizens are at risk they press the red button, which displays a protective sheet which covers the entire city.
